Updated with information on new "secret menu" items.
NEW YORK (TheStreet) -- For some fast-food patrons, a restaurant's menu isn't good enough. They prefer to create their own menu items by mixing and matching existing ingredients.
The best ones often end up on so-called "secret menus." They exist, but only for those in the know -- restaurant employees won't necessarily tell you about them.
Some items have become so popular by word-of-mouth that they're no more secret than what the restaurant has on its official menu. Ever heard of In-N-Out's "Animal Style" burgers and fries? Not on the menu board, but order it at the counter and you'll get it -- no questions asked.
Luckily for us, some fast-food employees are taking note of popular secret menu items. Last week, a Reddit user claiming to be a manager of a McDonald's in the UK held an AMA, or "Ask Me Anything," where she answered questions on her experiences working at the fast-food chain.
When asked about the validity of "secret menu" items, the manager responded:
"You can order from the 'Secret Menu'. Just like with any of our sandwiches, you can add, remove or change ingredients by special request. These are called 'grill orders' (i.e. Big Mac no pickle)
The items on the 'secret menu' weren't invented by anyone officially at McDonald's, it's just a random persons guide to burgers you could potentially 'hack' at McDonald's.
Order one and the workers might not know it by name (i.e. Land, Air and Sea burger or the McGangBang) but if you explain what it is, and are willing to pay for all the ingredients, it's just another 'grill order' that we can make up."
The Secret Menus Web site keeps a running list of interesting fast-food combinations and lesser-known options submitted by fans across the U.S. Click through our list below for some of the menu items we particularly like.
The Mc10:35: McDonald's
As its name suggests, this sandwich is only available for a limited amount of time each day, if at all. If you're able to get to McDonald's between the breakfast and lunch times (about 10:30am to 11am), you may be in luck. To make one of these sandwiches, order an Egg McMuffin and a McDouble. Then, put the beef patties inside the McMuffin yourself, and enjoy a fast-food brunch.
The Land, Sea, and Air Burger: McDonald's
This gigantic burger is not for the faint of heart. If your server is unfamiliar with this celebration of the elements, ask for a Big Mac (land) and add a fish filet (sea) and chicken filet (by a stretch of the imagination, air).
The McCrepe: McDonald's
If you're craving a less traditional, but classier, fast-food breakfast item than what is on the McDonald's menu, then look no further than the McCrepe. This is a DIY secret menu item, so simply take an order of hotcakes and spoon the contents of a yogurt parfait into each one.
Dirty Chai: Starbucks
Your server is likely to be familiar with the drink. If not, just ask for a chai latte (iced or hot) with a shot of espresso. The addition of espresso highlights the spices and herbs found in the black tea, making a delicious menu option even better.
Butterbeer Latte (Hot): Starbucks
Looking for a warm Butterbeer, but nowhere near Hogsmeade? This Harry Potter favorite can be easily created at Starbucks just as easily as any other custom drink. Ask for a whole milk steamer with two to four pumps each of caramel, toffee nut, and cinnamon dolce syrup. You can also add whipped cream and salted caramel bits on top, and if you need caffeine, add a shot of espresso.
Twix Frappuccino: Starbucks
The unmistakable flavors in a Twix bar can quickly rid anyone of a nagging craving for sweets. To mimic those flavors in your Starbucks Frappuccino, order a caramel frappuccino and add one to two pumps each of caramel and hazelnut syrup and a spoonful of java chips. Drizzle mocha and caramel on top and Twix fans will find themselves in heaven.
Shack-Cago Burger: Shake Shack
To get this ShakeShack burger, you have two options:
Order the Chicago style hot dog, remove the relish, onion, cucumber, pickle, tomato, mustard, celery salt and peppers and add them to your burger. This option leaves you with a hot dog, which you can share or eat on your own.
If you don't want the temptation of another hot dog after you've finished your burger, or you're worried about making a mess, you can just ask for the Chicago-style toppings on your burger.
For those who have never heard of Poutine, it is a Canadian dish that is not as complicated as it may sound. Ask for cheese curds and gravy on top of your order of French fries, and finally see what all the fuss is about up north.
Cheese Fries: Five Guys Burgers & Fries
This order is one of the easiest on this list because it only consists of two things: melted cheese and fries. But don't underestimate its simple ingredients: Once you've been introduced to Five Guys Cheese Fries, you'll never look back.
Tired of always ordering a burrito, but still looking to suppress your craving for Chipotle? Ask for an order of nachos, which will give you all the toppings of a burrito with a satisfying crunch.
Like the previous entry, the Quesarito isn't for anyone counting calories. To make this uniquely named dish, don't assume your cashier will know what you're talking about. Ask for a quesadilla, send it along the Chipotle line, and add all of your favorite burrito mix-ins. When it's finished, have it rolled up like a burrito. It's best to ask for one when there aren't many people waiting behind you as it takes a lot of time and effort for employees to make.
Chicken Quesadilla: Chick-fil-A
Not many people know that there are tortilla wraps behind the Chick-fil-A counter. What they do know is the restaurant chain has fantastic chicken and cheese, so why not add these together to make a delicious Mexican favorite?
Fried Chicken Club: Chick-fil-A
If you're a health-conscious eater looking to justify eating a less-than-healthy fried chicken sandwich, try ordering the Fried Chicken Club at Chick-fil-A. Servers are likely to know just what you're looking for, but if they aren't sure, ask them to add a few vegetables (and maybe some bacon) to a fried chicken sandwich. This meal isn't significantly healthier than the original fried chicken sandwich, but at least you'll get some greens!
Blueberry Cheesecake Milkshake: Chick-fil-A
If you're on a diet, this milkshake isn't for you. However, if you're looking to splurge (or share) something especially decadent, then Chick-fil-A has you covered. Unfortunately, this item will take a bit of luck, since not all Chick-fil-A's have blueberry cheesecake available. But if they do, just ask for a slice to be blended into your vanilla milkshake.
The Grand Slam: Wendy's
Wendy's is known to boast that its "hamburgers are made from fresh, never frozen beef," and the Grand Slam is a sure way to enjoy them. This burger consists of four thick, all beef hamburger patties in addition to your choice of cheese and vegetables.
Veggie Burger: Burger King
For those looking for a meatless option at the drive-thru that's more substantial than a side order of fries, look no further than the veggie at Burger King. It's not often advertised, but it gives vegetarians a way to enjoy a Whopper without the meat.
The Incredible Hulk: Taco Bell
This modified version of Taco Bell's famous 5-layer burrito is perfect for any guacamole lover. Ask your server to replace the burrito's melted cheese with guac, and watch as the people around you turn green with envy.
Butterfinger: Jamba Juice
The next time you're at Jamba Juice, ask for 12 oz. of carrot juice, and mix in chocolate, peanut butter, two scoops of frozen yogurt, and ice. With those kinds of ingredients, maybe it's (sort of) healthy.
